Astronauts at the International Space Station are spending more time away from Earth, but they still need their daily serving of vegetables. In the quest to find a viable way for crew to grow their own veggies while orbiting — and possibly one day on the moon or Mars — student researchers are sending broccoli…

Researchers from the University of Washington and several small companies have conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a probiotic — or natural microbe — to clean up groundwater contaminated with trichloroethylene, or TCE.

Plants can better tolerate drought and other stressors with the help of natural microbes, University of Washington research has found. Specifically, plants that are given a dose of microbes stay green longer and are able to withstand drought conditions by growing more leaves and roots and using less water.

Scientists using a microbe that occurs naturally in eastern cottonwood trees have boosted the ability of willow and lawn grass to withstand the withering effects of the nasty industrial pollutant phenanthrene.
